Letters Patent No. 94,271, dated August 31, 1869.

IMPROVMENT IN RAIN-WATER STRAINERS AND CUT-DIES.

The Schedule referred to in these Lettere' Patent and making part of the same.

ToaZL whom it may concern:

Be it known that I, SAM'UEL Avnss, of Danville, in the county of Boyle, and State of Kentucky, have invented anew and improved VStrainerand Gut-'Off for Gisterns; and I do hereby declarethat the following is a full, clear, and exact description thereof, which will enable others skilled in the art. to make and use the same, reference being had to the accompanying drawings, forming part-of this specieation, in which- Figure 1 represents a vertical longitudinal section of' my improved strainer and-cut-oi, the plane of section being indicated by the linea: x, viig. 2.

Figure 2 is a front view of the same. Similar letters of reference indicate corresponding parts.

This invention relates toa new apparatus for straining the water rnnningfrom a roof into a cistern, `and for cutting it oi' when it is to be conducted into a garden orsolne other place, or to preventoveriiowing ofthe cistern.

The invention consists chieflyA in a sliding trough, which can be moved under the water-course, to prevent the water from reaching the cistern, and which may be again moved out of the way to free the passage to the cistern.

The invention also consists in several devices and appliances for preventing leaves and other impurities from clogging the strainer'.

A A, i the drawing, represents a pipe, arranged between the roofl and cistern of a building, on the ordinary rain-water pipe.

The portion A of the said rain-nnterfpipe is by preference made square, with an enlargement,a, on one side, as shown.

The enlarged portion a carriesa sieve oi strainer, b, which is or may be inclined as shown, to allow leaves, Ste., to iind their wayout through the open vfront part of the pipe.

The sieve will 'arrest all leaves, insects, and other: impurities, and will prevent their. entering the cistern.

Above the sieve are arranged, ou the. inner sides of the enlarged part ofthe pipe A, some inclined rails, c, on which the turned-over` edges of an inclined trough, B, are suspended.

This trough is held in place by a wire hail, d, which' When the trough is down, to let the strainer work, i

it can be swung up, asshown by red lines, 2, in iig. 1, to allow the strainer to be cleaned.

To prevent the sides ot' the bail from becoming clogged by leaves or other impurities, they are protected by inclined flanges f f, vas shown in iig. 2, said anges also serving to direct the' water to the centre ofthe pipe.

Having thus described my invention,

I claim as new, and desire to secure by4 Letters Patentl. The combination of the movable trough B, bail d, and pipe A, as and for the purpose specified.

2'. The construction and arrangement with reference to each .other of the bail d, pipe A, and flange f, for the purpose set forth.

SAMUEL AYRES.
